hi! I need a good partner for mega absol providing good offensive synergy able to take Down most pokes mega absol cant take. I was thinking off hydreigon, fast pseudo-powerhouse able to take Down almost any Pokemon With specs. and absol can then late game sweep. but the problem is that, that would give teribble fairy weakness. should I just stick With hydreigon or have you someone to recomend?
heres the set:

I personally always like flamethrower, as it nails steel types like metagross as well as tan growth and avalugg, and play rough nails all the fighting types psychology cut gets except toxicroak while also getting medicham and scrafty. I guess it's good for the nidos and crobat.

First up is Cofagrigus who can pull off a mixed wall set with WoW and SDef EVs. It's great bulk allows it to tank a large number of hits, and it resists Absol's weaknesses. Shadow Ball is STAB while Energy is to get the drop on lots of tanky Pokemon like Rhyperior and Swampert.

Another option is Roserade who can tank a huge number of special attacks while also setting up some Toxic Spikes to harm your foe. Synthesis is recovery while Giga Drain and Sludge Bomb are STABs and provide good coverage.

Last off is Specs Chandelure who can provide some offensive support for Absol with a good variety of powerful Special Moves. It would also allow you to switch over to Psycho Cut on Absol which is a far better option. Trick screws over a lot of opposing walls who could potentially tank Absol's attacks.
